Usage

From source file:MapEntrySetDemo.java

public static void main(String[] argv) {

    // Construct and load the hash. This simulates loading a
    // database or reading from a file, or wherever the data is.

    Map map = new HashMap();

    // The hash maps from company name to address.
    // In real life this might map to an Address object...
    map.put("Adobe", "Mountain View, CA");
    map.put("IBM", "White Plains, NY");
    map.put("Learning Tree", "Los Angeles, CA");
    map.put("Microsoft", "Redmond, WA");
    map.put("Netscape", "Mountain View, CA");
    map.put("O'Reilly", "Sebastopol, CA");
    map.put("Sun", "Mountain View, CA");

    // List the entries using entrySet()
    Set entries = map.entrySet();
